To treat Cicada Killers, you can discourage the wasps from nesting in your yard by cutting your grass on the highest setting and by adding a thick layer of mulch to flower beds during the Cicada Killer Wasp season. These wasps do not like over-saturated lawns either, so over-watering during their season will help prevent them. Unfortunately, there is no foolproof way to prevent cicada killer wasps. For current infestations, you would need to use Delta dust in each individual burrow. Using a residual like Suspend SC will also kill them when they come in contact with the treated areas.
